Abstract: Blockchain is essentially a distributed database or a network database. A real smart contract should be legally effective chain code, namely, the digitization of legal contracts, and can realize the automatic execution of contract terms. This article firstly introduces important technologies relevant to this type of smart contract, including legal considerations, oracles, event models and others, then proposes five standard development steps for legal smart contracts and a method for designing smart contract templates. Moreover, we also design a secure multi-channel event model for data preprocessing. Consequently, contracts processed on the above smart contract platform are expected to have legal effect.

Key words: oracle machine, smart contract, law, secure multi-channel event model
